Abstract
A possible effect of spin fluctuations on the electric field gradient in Cu-0 layers in HTSCS is studied by the phenomenological antiferroma gnetic Fermi-liquid theory of Millis et al. Our theoretical analysis s uggests that the coupling between the quadrupole charge density and th e spin fluctuations in the two-dimensional 'metallic' Cu-0 layers is t he origin of the temperature dependence of Cu-63 NQR frequencies at th e Cu(2) sites in YBa2Cu3O7-delta.
